The system uses a series of nested bags to guide content - much like my nested Glyph system used in Borderlands-scape (which sadly, never went public before computer crash years ago)

Today (Nov. 10, 2018 ), I created a Quest Item Bag, which helps keep track of and guide the player on their quest progression.
With the Quest Item Bag, I also updated some all-purpose language to more specific Quest Item referencing.

Which reminds me.. I need to update the Challenge Bags to utilize Quest Item Bags...
but that must be for another time!
